Synthesis and characterization of Li [ (Ni0. 8Co0. 1Mn0. 1) 0.8 (Ni0. 5Mn0. 5) 0.2] O2 with the microscale core− shell structure as the positive electrode material for lithium batteries J. Mater. Chem., 4 (13) (2016), pp. 4941 - 4951 J. Mater.
Ultimately, the development of electrode materials is a system engineering, depending on not only material properties but also the operating conditions and the compatibility with other battery components, including electrolytes, binders, and conductive additives. The breakthroughs of electrode materials are on the way for next-generation batteries.
In 2017, lithium iron phosphate (LiFePO 4) was the most extensively utilized cathode electrode material for lithium ion batteries due to its high safety, relatively low cost, high cycle performance, and flat voltage profile.
Hence, the current scenario of electrode materials of Li-ion batteries can be highly promising in enhancing the battery performance making it more efficient than before. This can reduce the dependence on fossil fuels such as for example, coal for electricity production. 1. Introduction
Summary and Perspectives As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials.
This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity. Many of the newly reported electrode materials have been found to deliver a better performance, which has been analyzed by many parameters such as cyclic stability, specific capacity, specific energy and charge/discharge rate.
